A 15 kilogram object moves up the y-axis at a constant

Question

A 1.5 kilogram object moves up the y-axis at a constant speed. When it reaches the origin, the forces F₁=5.0 Newton at 37 degree above the + x-axis, F₂=2.5 Newton in the +x-direction, F₃=3.5 Newton at 45 degree below the-x-axis, and F₄= 1.5 Newton in the -y-direction are applied to it.

(a) Determine will the object continue to move along the -y-axis?

(b) If not, find what simultaneously applied force will keep it moving along the y-axis at a constant speed?
